## Abstract

We are adopting a new airworthiness directive (AD) for certain General Electric Company (GE) CF34-8E turbofan engines. This AD was prompted by a report from GE regarding a quality escape of nonconforming thrust reverser fire seals. This AD requires a one-time inspection of the gap between the core cowl seal and the pylon seal of the thrust reverser for correct gap width, and replacement of the seals, if needed. We are issuing this AD to address the unsafe condition on these products.
